CONCLUSION The surgical treatment for cervical esophageal carcinoma should be decided by the location of the tumor,the extent of the cancer involved and lymph node metastasis.

PURPOSE: The aim of this study is to further understand the status of BRCA1 and BRCA2 mutation among Chinese high-risk breast cancer patients in multiple-ethnic regions of China. METHODS: A total of 79 blood samples of high-risk breast cancer patients from Xinjiang Uyghur autonomous region were analyzed by PCR-DHPLC sequencing analysis. RESULTS: Analysis with full length of the two genes identified a total of 6 deleterious mutations (2073delA, 2394C-T [Q759X] and IVS16+1G>A in BRCA1; 1627A-T [K467X], 6873delCTCC and 9481delA in BRCA2) in this cohort. The prevalence of BRCA1/2 germline mutation was about 7.6% (6/79) in the Xinjiang multiple ethnic region of China. Among them, 3 novel deleterious mutations, 2073delA in BRCA1 (Han ethnic Chinese) and BRCA2 variants 6873delCTCC and 9481delA (both are Kazakh ethnic Chinese), were identified and they had never been reported in breast cancer information core (BIC) database before. 2394C-T (Q759X) and IVS16+1G>A, in BRCA1 and BRCA2 variants 1627A-T were previously reported in other populations but not Chinese. Among 6 of the BRCA-related tumors, three BRCA1- and one BRCA2-associated tumors were in triple negative (estrogen receptor, progesterone receptor, and HER2 negative expressed) status and exhibited a high tumor grade. So far none of these 6 deleterious mutations were reported in ethnic Han Chinese. CONCLUSION: BRCA germline mutation in Chinese multiple ethnicity region may exhibit different genotypes compared to ethnic Han Chinese in other regions. These differences may arise from interaction of genetic background and environmental factors.

Objective:To analyze the improvement effect of monk fruit on diabetic nephropathy(DN)by network pharmacology,and to elucidate its possible related mechanism.Methods:The Traditional Chinese Medicine Systems Pharmacology(TCMSP)Database was used to detect the active ingredients and their targets of monk fruit;the DN target genes were screened out by DisGeNET Database and Genecards Database;the key targets of monk fruit against DN were obtained by comparing the monk fruit with DN targets;protein-protein interaction(PPI)network diagram was constructed by STRING Database and Cytoscape software;Gene Ontology(GO)functional enrichment analysis and Kyoto Encyclopedia of Genes and Genomes(KEGG)signaling pathway enrichment analysis were performed by Cytoscape software.Molecular docking technology was used to predict the binding abilities of the core targets and the main active ingredients of monk fruit.Results:The TCMSP Database combined with the selection criteria was used to screen out a total of five active ingredients of monk fruit(ZINC03860434,Perlolyrine,beta-sitosterol,Kaempferol,and Flazin)as well as 85 targets represented by serine/threonine protein kinase 1(AKT1),transcription factor RELA,c-Jun N-terminal kinase(JUN),and tumor necrosis factor(TNF).Among them,Kaempferol contained the most targets.Among the 85 targets,34 were associated with DN.The GO functional enrichment analysis mainly included biological process(BP)such as oxidative stress,regulation of inflammation and apoptosis,and cell signaling transduction.The KEGG enrichment analysis included advanced glycosylation end product(AGE)-receptor of AGE(AGE-RAGE)signaling pathway,TNF signaling pathway,and C-type lectin receptor signaling pathway.The results molecular docking technology of the main active ingredients of monk fruit and DN target proteins showed that 5 kinds of molecular docking engergy were-8.00--5.00 kJ·mol-1.Conclusion:Kaempferol is the most effective active ingredient in the monk fruit for the treatment of DN,and its mechanism is mainly related to anti-inflammatory.

OBJECTIVETo introduce the design and application of the expanded transposition skin flap in the treatment of cheek skin defects.

METHODSThe expanded transposition flaps were divided into three types: the regular expanded transposition flap (ERT flap), the expanded transposition-advancement-transposition flap (TAT flap) and the expanded rotation-advancement-transposition flap (RAT flap). 135 cases of cheek skin defects resulted from hemangioma, scar and naevi were treated with these three types of flaps. Delay surgery was needed when the ratio of length to width was bigger than 2 : 1.

RESULTSThere were 139 expanded transposition flaps, including 17 ERT flaps, 69 TAT flaps, 53 RAT flaps. Blood supply disturbance was happened at the end of the flaps in 6 cases, including 2 ERT flaps and 4 other flaps. Other flaps had no complication. The results were satisfactory.

CONCLUSIONSThe expanded transposition skin flap is a reliable method to repair the cheek skin defect. The preoperative flap design is very important for successful reconstruction.

BACKGROUNDAtopic dermatitis (AD) is characterized by defective skin barrier and imbalance in T helper 1/T helper 2 (Th1/Th2) cytokine expression. Filaggrin (FLG) is the key protein to maintaining skin barrier function. Recent studies indicated that Th1/Th2 cytokines influence FLG expression in keratinocytes. However, the role of Th1/Th2 cytokines on FLG processing is not substantially documented. Our aim was to investigate the impact of Th1/Th2 cytokines on FLG processing.

METHODSHaCaT cells and normal human keratinocytes were cultured in low and high calcium media and stimulated by either interleukin (IL)-4, 13 or interferon-γ (IFN-γ). FLG, its major processing proteases and key protease inhibitor lymphoepithelial Kazal-type-related inhibitor (LEKTI) were measured by both real-time quantitative polymerase chain reaction and Western blotting. Their expression was also evaluated in acute and chronic AD lesions by immunohistochemistry.

RESULTSIL-4/13 significantly reduced, while IFN-γ significantly up-regulated FLG expression. IL-4/13 significantly increased, whereas IFN-γ significantly decreased the expression of kallikreins 5 and 7, matriptase and channel-activating serine protease 1. On the contrary, IL-4/13 significantly decreased, while IFN-γ increased the expression of LEKTI and caspase-14. Similar trends were observed in AD lesions.

CONCLUSIONSOur results suggested that Th1/Th2 cytokines differentially regulated the expression of major FLG processing enzymes. The imbalance between Th1 and Th2 polarized immune response seems to extend to FLG homeostasis, through the network of FLG processing enzymes.

Objective: To explore the relationship betweenrheumatoid arthritis (RA) and chronic periodontitis (CP). Methods: A total of 48 RA patients were recruited from the Rhematology Department of The First Affiliated Hospital of Shantou University Medical College (SUMC). RA patients were matched on age and gender with healthy controls, who were recruited from the Stomatology Department. Dental parameters including unstimulated salivary flow rate(UWS), stimulated salivary flow rate (SWS), bleeding on probe (BOP), periodontal probing pocket (PD), clinical attachment level (CAL) and decayed, missing and filling (DMF) were recorded in all cases. Erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) and Anticyclic citrullinated peptide antibody (Anti-CCP) were also recorded in RA patients. Results : There were significant difference between RA group and health control group on salivary flow rate, BOP, PD, CAL and DMF (P< 0.001). Higher percentage of RA patients were diagnosed as periodontal disease than those in control group (P< 0.001). There was relationship between CAL and Anti-CCP antibody (P< 0.001). Conclusion RA patients have higher risk of CP, and there might be relationship between RA and CP.

Objective: To investigate the risk factors of chronic obstructive pulmonary disease (COPD) in Li and Han ethnic group in Hainan, China. Methods: All subjects were randomly selected from various regions in Hainan. General characteristics were compared between COPD cases and healthy control cases in both Li and Han ethnic groups. The odds ratio (OR), the corresponding 95% confidence interval (CI) of COPD were calculated by logistic regression. Results: A total of 277 Li COPD cases, 307 Li healthy control subjects, 290 Han COPD cases and 301 Han healthy control were included in this study. In both the Li and Han groups, the average age exceeded 65 years, and the cigarette number smoked per day and the smoking duration were correlated with risk of COPD. In the Li COPD subjects, low weight, smoking, and recurrent infection of respiratory tract were mainly risk factors; while the mainly risk factor of Han COPD subjects was family history of respiratory disease. Conclusions: The risk factors are different in COPD subjects of Han and Li nationalities in Hainan of China. The age and smoking are strongly correlated with COPD risk.
